This:
"when I go to edit, I only can choose for add backup and not add template or add group"
is probably going to require that a case to be opened and have the problem analyzed
"Is it possible to copy my 7.11 oracle an SAP backup definitions from my "old" 7.11 Unix Cell Server to this new 8.12 Windows cell server?"
I'm not sure what is meant by "7.11", there was no such version. However, all Oracle Backup specifications are kept in the 'folder
Program Files -> Omniback -> Config -> Server -> Barlists -> Oracle8
and SAP backups are kept in
Program Files -> Omniback -> Config -> Server -> Barlists -> SAP
They should be able to be copied directly from your old server
